NOAA Climate Change report 2021: Global Temperature Rebecca Lindsey, Luann Dahlman Published March 15, 2021, updated August 12, 2021 Highlights •

Earth’s temperature has risen by 0.14° F (0.08° C) per decade since 1880, and the rate of warming over the past 40 years is more than twice that: 0.32° F (0.18° C) per decade since 1981.

•

2020 was the second-warmest year on record based on NOAA’s temperature data, and land areas were record warm.

•

Averaged across land and ocean, the 2020 surface temperature was 1.76° F (0.98° Celsius) warmer than the twentieth-century average of 57.0°F (13.9°C) and 2.14˚F (1.19˚C) warmer than the pre-industrial period (1880-1900).

•

Despite a late-year La Niña event that cooled a wide swath of the tropical Pacific Ocean, 2020 came just 0.04˚ Fahrenheit (0.02˚Celsius) shy of tying 2016 for warmest year on record.

•

The 10 warmest years on record have occurred since 2005.

•

From 1900 to 1980 a new temperature record was set on average every 13.5 years; from 1981–2019, a new record was set every 3 years.

Comments by John Shanahan, Founder of website: allaboutenergy.net We don't raise a question about NOAA’s climate data although others do raise the question of manipulation and misinterpretation.

We question conclusions about atmospheric CO2 being the main driver of Earth's climate and claims that controlling atmospheric CO2 will control Earth's climate.

Furthermore, we question claims that extracting CO2 from the atmosphere or limiting emissions from fossil fuels will control CO2 in the atmosphere. We think that CO2 emissions from vast CO2 reservoirs in the oceans and life on land are dominant controls of long-term atmospheric CO2.

Data from good sources, properly interpreted, and not altered to go along with desired conclusions are essential in verifying scientific theories.

The idea of "establishing" one temperature number to a decimal for "Earth's temperature" and using that to decide policy about the most important energy source, fossil fuels, and imposing very questionable energy sources of wind and solar are terrible leadership with tragic hidden agendas.

Some people are experts on life in the mountains. They understand the "lag time" of signs of winter changing to spring at different locations and elevations. That "lag time" is in the order of weeks and months across continents.

The lag time between globally averaged atmospheric temperature change and atmospheric concentration of CO2 is in the order of 100 to 800 years. Change in atmospheric CO2 generally FOLLOWS change in temperature, as can be shown with any carbonated drink that starts out carbonated and cold and gets warmer and goes flat. The climate alarmists insist that it is the other way around. If atmospheric CO2 would be a major leading driver of Earth's single data point average temperature, there would be at least a 150 year lag time because of the tremendous thermal inertia to change the temperature of the entire volume of the oceans. Change in atmospheric CO2 in 1870 would determine the Earth's temperature in 2020, not any change in atmospheric CO2 in the last decade determining Earth's single data point temperature in the last decade.

Conclusions that atmospheric CO2 is the major driver of temperature change disagree with the climate history of the Earth and physics of the sun’s energy interacting with carbon dioxide molecules in the atmosphere.

This is demonstrated in hundreds of articles by authors around the world on the website: allaboutenergy.net. The public can understand this just as they can understand why the soda pop goes flat when the can is opened and left to warm up for a few days.

Alarmists with poorly disguised agendas to control Earth's human population and gain power over others ignore basic physics and climate history.

Nature and humanity are in constant struggles of opposing interests and objectives. The struggle over man-made global warming alarmism and use of fossil fuels should be settled sooner rather than later.

There is no good reason to abandon the benefits of fossil fuels and their by-products.
